In order to investigate the possibility on the developing higher value-added products by recycling steel industry slags,the hydrothermal treatment and hydrothermal hot pressing were madeusing BF slag and quartz or flyash.The characterization of fabricated pellets was made on the mechanical strength and micro hardness,as well as XRD analysis and SEM observation.In the hydrothermal treatment,the tobermorite(5CaO?6SiO2?5H2O)phase was found in XRD patterns for the samples with 20%,30%and 40%quartz addition and with 10%flyash addition.The tobermorite peaks were shown for the sample with 10%flyash addition.Maximum strength was found on the samples with 20%quartz addition and 10%flyash addition.However,the hydrothermal reaction in the mixed powder was not active in the hydrothermal hot pressing in the present experimental condition.Improvement in the experimental parameters will be necessary to get hydrothermal reaction in the process of hydrothermal hot pressing.

为了探索在现有原料条件下不同TiO2 对高钛型磁铁矿烧结性能的影响，通过实验得出，在烧结矿中TiO2含量6％～10％内，随着TiO2 含量增加，混合料初熔和熔化温度均上升，烧结矿强度和成品
Pb-C电池具有安全性好、价格低、高倍率部分荷电状态（HRPSoC）下循环寿命长等优点，是混合电动汽车（HEV）较为理想的动力电源。但是Pb-C电池由于负极碳含量高，存在较为严重的析氢问题，导致电池因失水而过早失效，因此研究消氢催化剂对降低Pb-C电池失水，改善Pb-C电池性能具有重要意义。本研究首先优化了泡沫碳的制备工艺，通过化学镀和电镀的方法在其表面沉积一层贵金属钯得到泡沫状消氢催化剂。将其置
